Partial discharge location detection method and device, readable storage medium and electrical equipment

Abstract

The invention discloses a partial discharge location detection method and a device, a readable storage medium and electrical equipment. The method comprises the following steps: acquiring partial discharge data in the electrical equipment, building a radio frequency spectrum database, and building a forecasting regression model, wherein the partial discharge data has a known sample and an unknownsample; performing feature extraction on the partial discharge data of the known sample in the radio frequency spectrum database; performing dimension reduction processing on the partial discharge data of the known sample after the feature extraction; optimizing the partial discharge data of the known sample after the dimension reduction processing through a particle swarm algorithm, and calculating position coordinates of the partial discharge data of the unknown sample. According to the technical scheme, location accuracy of detecting the partial discharge location in the electrical equipment is improved.

Description

Technical field [0001] The present invention relates to the field of discharge detection technology, in particular to a method, device, readable storage medium and electrical equipment for partial discharge location detection. Background technique [0002] Electrical equipment is the basic component of the power system and the basis for ensuring the reliability of power supply. The deterioration of the insulation performance of electrical equipment is the main cause of its failure. In severe cases, it may cause a large-scale blackout of the power grid. Partial discharge is not only a symptom of insulation deterioration of electrical equipment, but also a key factor causing insulation deterioration. In substations, transformers are prone to partial discharge. Partial discharge occurs when the discharge part between conductors is connected to an insulator. When the electric field strength is greater than the breakdown strength of the insulator, the discharge is often highly concen...

Problems solved by technology

However, in the traditional scheme, the discharge of the overall equipment is detected, the detection accuracy is relatively low, and the stability is not high, especially under the condition that multiple transformers exist at the same time, the expected effect cannot be achieved.
